The chart above, part of a presentation by game designer Jesse Schell at Gamelab today, shows data put together by analytics company EEDAR.
The slide shows that an average Xbox 360 game with -
- a trailer but no demo sells 520,000 units
- a trailer and a demo sells 250,000 units
- no trailer and a demo sells 200,000 units
- no trailer and no demo sells 100,000 units
- in a six month period.
As CVG say, though this doesn’t take into account which games are analysed or whether the big AAA games (like Call of Duty) that don’t run with demos (or don’t have them until after release) would make any difference.
On the Xbox 360, Arcade games have to have a demo. Would a substandard demo put people off? Can a publisher twist what a game is like with an unplayable trailer?
